REXX is 15 years old as of March 20, 1994.
Until an ANSI standard is completed, the language is defined in "The REXX Language: A Practical Approach to Programming" by M. F. Cowlishaw, Second Edition, Prentice Hall, ISBN 0-13-780651-5, often referred to as "TRL".
REXX implementations are available for VM/CMS, MVS/TSO, OS/2, PC DOS, UNIX, Macintosh, others, and now CICS!
